National police chief Pol Gen Damrongsak Kittiprapas has ordered highway police to investigate an allegation that drivers of overloaded trucks displaying special bribe-paid stickers are not being arrested.
Police spokesman Pol Lt Gen Archayon Kraithong said on Monday that Pol Gen Damrongsak wanted the Highway Police Division to quickly get to the bottom of the allegation.
Any officers who were involved in such bribery would face decisive action, including expulsion from the force.
The Highway Police Division earlier reported it cooperated regularly with the Land Transport Federation of Thailand and stopped overloaded trucks, the spokesman said.
The national police chief would welcome any information from the public about the alleged racket, so the police could tackle it, Pol Lt Gen Archayon said.
Wiroj Lakkhanaadisorn, a list MP-elect of the Move Forward Party, recently posted on social media that he was compiling evidence of the police racket. He claimed overloaded trucks with special stickers were not being detained and the drivers arrested at weighbridges.
The stickers variously depicted rabbits, a smiling sun or kungfu panda, and were available at a cost of thousands of baht per month, he said.
